A World to Explore

Archive for July 4th, 2009

We’re on the Skagi Peninsula now and internet access is a little more random. We started field work on Rob’s and Adam’s projects this week. Rob found some awesome zeolites – too many to name – and a lot of altered basalt (my poor babies!). Adam ran into some trouble early on because many of the rhyolites appear highly altered, but has managed to find some pretty decent samples that he can use for geochemical analyses.

Adam conquers Vatnsdalsfjall on his way to the top to sample rhyolites.

We’re living in a house with 12 people – sounds like a reality show (The Geology World or Big Brother: Geo-Style). Meagen is in a room with 4 girls – it looks like their clothes exploded. Todd, Rob, and Adam are sharing a room – it smells…refreshing(?). They have swum in the arctic ocean EVERY DAY since we arrived. They are CRAZY!

We’re going to be here until July 14. Sadly, we’ll be missing the Hunavaka, a local celebration with colorful balloons and music. Still, every day is a celebration when you’re doing geology!

KAUGATUMA, SAAREMAA, ESTONIA–It is always an important moment for a Wooster geology research team when it identifies its final student independent study project. Today Palmer Shonk found his. There is a remarkable exposure of a high-energy deposit in the Aigu Beds (Kaugatuma Stage, Upper Silurian) on the Sõrve Peninsula of southwestern Saaremaa island. These rocks have spectacular crinoid materials, including elaborate holdfasts, along with stromatoporoids, bryozoans and brachiopods. The sediments still retain their original dune bedding forms showing the high energy conditions under which they were deposited.

Palmer and Rob at the Kaugatuma locality (N58.12409°, E22.19375°). I probably shouldn't point out again the spectacular weather. That would be like bragging.

Palmer’s job will be to understand the original organisms and the environments in which they lived and died (a paleocommunity study) as well as the means by which the remains were redistributed and preserved (a taphonomy study). It is exciting material which will make an excellent project.

At the end of the day we said good-bye to our generous and thoughtful Estonian hosts Olev and Ingrid Vinn. We are on our own now in Estonia, but they’ve trained us well. They left us at the marvelous Kaali Meteorite Craters, estimated to be about 7500 years old.

The main Kaali meteorite crater. On the far side of the pond you may see a spot of blue. That is Rob McConnell performing his job as a scale very well.
